explain the difference between user EXEC mode Privilege EXEC

explain the difference between user EXEC mode, Privilege EXEC mode and Global configuration mode

Solution

USER EXEC MODE

-User can type in harmless EXEC commands, harmless, as it wont hurt the routers operations, and EXEC as the router takes the command executes its and give you an output.

-When you are in the user mode you will see ‘>‘ at the command prompt

-There are no configurations done, this mode is just to view various configurations of the router.

Some of the commands include,

PRIVILEGED EXEC MODE

-This mode allows users to VIEW all configurations on the router and allow to change some less important configuration, there are a few commands that work on both User EXEC and Enable mode, basically Enable mode is a high privileged User EXEC, with more power to use the router.

-You can do various things, like changing the hostname of the router, adding password to this mode, see the running-configuration of the router and more, BUT, you can configure the router or get the root access to make changes to how the router operates in a network, for that you need to get into Global Configuration mode.

GLOBAL CONFIGURATION MODE

This is the root access, privileged level 15 mode, where you have the root access to the router, you can do the configuration, change the IOS version, backup, restore and more.

Router(config)#

-Notice (config) before that # indicating that it is in Global Configuration mode.

-To enter the Global configuration mode from the Enable mode you have to enter configure terminal in the Enable mode, to return back type End or Exit or press Ctrl+z
